Duluth, in the county of St. Louis and-State In constructing said throat and manifoldv of Minnesota, have invented certain new t e inner bends of the conduit as at 3, so a rapidly To all whom z'tmay concern:

do declare the following to be 60 a specification. I r

y invention relates to fuel ductors for internal explosion engines and Upon the inner faces of the' p outward bends of said conductor and at such deflecting into the stream of yapor the films other points, if any, as ma be desired, as of liquid which tend to cling to certain walls at 3, 3, 3, form ri e plates or ribs of t e carburetor throat and of the manifold of any suitable form, as 3 3, which extend and to flow into the cylinders in liquid form.

transversely of the conduit across the path Such tendency is especially apparent inlow of the liquld film. Said ribs are preferably grade gasoline and-is facilitated by curvedcrescent shaped transversely of the conduit thinner at their ends than in their centers. ere such ribs appearon opposite walls, they are preferably staggered with respect to each other, as at 3, 3. Said ribs may have an suitable profiles adapted 66 to deflect the fi n1 liquid from the wall some nf which One of the objects of mymventionis to introduce sharp angular the stream of vapor.-
